The baseboard management controller (BMC) provides the intelligence in the IPMI architecture. It is a specialized microcontroller embedded on the motherboard of a computer – generally a server. The BMC manages the interface between system-management software and platform hardware. BMC has its dedicated firmware and RAM.
The LO100 is a traditional IPMI BMC, and does not share hardware or firmware with iLO. ProLiant 100 series servers starting with Gen9 include iLO. There is also a version of iLO for HP Moonshot systems referred to as iLO Chassis Management which is often abbreviated as iLO CM.
The DRAC interfaces with baseboard management controller (BMC) chips, and is based on the Intelligent Platform Management Interface (IPMI) 2.0 standard, which allows the use of IPMI out-of-band interfaces such as IPMI Over LAN. [1]
The OpenBMC project is a Linux Foundation collaborative open-source project that produces an open source implementation of the baseboard management controllers (BMC) firmware stack. [ 1 ] [ 2 ] [ 3 ] OpenBMC is a Linux distribution for BMCs meant to work across heterogeneous systems that include enterprise, high-performance computing (HPC ...
That way, a common Ethernet connection becomes shared between the computer's operating system and the integrated baseboard management controller (BMC), usually by configuring the network interface controller (NIC) to perform Remote Management Control Protocol (RMCP) ports filtering, use a separate MAC address, or to use a virtual LAN . Thus ...
NC-SI, abbreviated from network controller sideband interface, is an electrical interface and protocol defined by the Distributed Management Task Force (DMTF). The NC-SI enables the connection of a baseboard management controller (BMC) to one or more network interface controllers (NICs) in a server computer system for the purpose of enabling out-of-band system management.
Data Center Manageability Interface (DCMI) is a data center system management standard based on the Intelligent Platform Management Interface (IPMI) but designed to be more suitable for data center management: it uses the interfaces defined in IPMI, but minimizes the number of optional interfaces and includes power capping control, among other differences.
The Shelf Managers communicate with each board and FRU in the chassis with IPMI (Intelligent Platform Management Interface) protocols running on redundant I²C buses on the Zone-1 connectors. The Base Interface is the primary Fabric on the Zone-2 connectors and allocates 4 differential pairs per Base Channel.
